A single shared runqueue O(n) strict fairness earliest deadline first design.
-Ultra low latency and excellent desktop performance.
+Ultra low latency and excellent desktop performance for 1 to many CPUs.
Not recommended for 4096 cpus.
Scalability is optimal when your workload is equal to the number of CPUs on
bfs. ie you should ONLY do make -j4 on quad core, -j2 on dual core and so on.
Features SCHED_IDLEPRIO and SCHED_ISO scheduling policies as well.
+You do NOT need to use these policies for good performance, they are purely
+optional.
To run something idleprio, use schedtool like so:
